Title: Data reproducing system of disk apparatus
Inventor: SAKO YOICHIRO
IPC: G11B19/28
Filed: 1990-11-16
Abstract: PURPOSE:To shorten an access time when a target track is sought by rotating a disk at a high speed so that read data transfer speed of the disk is sufficiently higher than the data reading speed from a memory. CONSTITUTION:An optical disk 1 is set to the vicinity of an upper limit of a rotating speed capable of reading by an optical head 3, and set to a highest transfer speed. The transfer speed is faster than signal processing and error data correcting speed of data to be supplied from storage means 8 in a signal processor 8. Accordingly, the means 8 is reduced in storage capacity during reproducing of the data as a time goes, and finally filled with recording data. Accordingly, unused storage capacity of the means 8 is monitored by a controller 10, and when the unused storage capacity becomes a predetermined value or below, a control signal is sent from the controller 10 to a servo circuit 7 to control a tracking actuator of the head 3, and data supply to the means 8 is temporarily stopped.

Title: Reciprocally cutting skiving machine
Inventor: TAKAGI MASAYOSHI
IPC: B23D39/00
Filed: 1986-12-27
Abstract: PURPOSE:To shorten the machining time, by enabling 180 deg. swivel positioning of a cutter table holding a broach around a normal to the longitudinal axis of the broach and cutting feed in normal direction, thereby halving the length of the broach and shortening the stroke of a cutting unit. CONSTITUTION:When a cutting unit is fed downward by a cutting feed motor 13, a work is skived by a broach 20. When the cutting unit reaches to the lower end position and the first time machining is finished, a swivel cutting table 12 is swiveled by 180 deg. to direct the cutting direction of the broach 20 upward so as to provide a predetermined cutting amount to a swivel base 11 by means of a cutting motor 14. Then the rotary direction of the work is reversed to feed the cutting unit upward so as to carry out skiving again. Since reciprocation of cutting unit functions to provide cutting feed, only half length of the broach 20 is required for same cutting amount. Consequently, stroke of cutting unit can be shortened resulting in shortening of machining time.

Abstract: PURPOSE:To accurately recognize the existence of a defect, etc., by preparing plural recognizing patterns with respective different patterns and recognizing the shape of a recognization object substance according to the synthetic result based on the matching of a picture with all these prepared plural recognizing patterns. CONSTITUTION:When a synthetic decision related to a defective part A is executed, in a CPU 4, it is not decided that 'a defect exists, and a defect type is A' only by the matching of one recognizing pattern 20a and a binarizing picture corresponding to the defective part A, but the synthetic decision is executed by synthesizing detected results of the matching of the other recognizing patterns 20b-e and the binarizing picture with that of the above-mentioned matching. In this case, in the CPU 4, when it is decided that 'no defect exists' with a recognizing pattern 20e, and moreover, it is decided that 'a defect exists, and a defect type is A' with at least three recognizing patterns or more out of the recognizing patterns 20a-d, this is made into a logic composed as 'a defect exists, and a defect type is A', and the synthetic decision is executed. Thus, the existence of the defect in the recognition object substance can be recognized correctly.

Title: Pressure regulation device for self-regulating valve
Inventor: HASEGAWA YOSHIHIKO
IPC: G05D16/20
Filed: 1990-11-15
Abstract: PURPOSE:To enable speedy convergence to set pressure by storing an operation output signal before correcting operation unless a deviation is converged although an operation output signal of correcting operation calculated according to the deviation is corrected by performing addition or subtraction continuously plural times, and outputting the operation output signal newly and returning a regulating means to its original position. CONSTITUTION:A regulator 40 is stored with the relation between the set pressure of the self-regulating valve and the regulation quantity of a regulating means 32, the position of the regulating means 32 corresponding to target pressure is clearly known, and a driving part 34 is operated to set the valve to the set pressure. If the self-regulating valve itself can not be set because of its mechanism, the correcting operation is further performed. When the deviation is not converged even after the correcting operation, an operation output is further added or subtracted at certain intervals of time and the result is outputted. If the deviation is not converged although the addition or subtraction is repeated plural times, it is judged that abnormality occurs and the operation output signal before the correcting operation which is stored in advance is outputted nearly to return the regulating means 32 to its original position. Consequently, when disturbance is removed, original pressure regulation is speedily performance and no overshoot is caused.

IPC: B05D1/02
Filed: 1986-12-27
Abstract: PURPOSE:To enhance the efficiency of a painting line by rapidly performing the next painting within a short time, by forming two systems of flow passages reaching two color change valves from a main pipe and by washing one of the flow passages while holding the other flow passage to a paint supply state. CONSTITUTION:The paint, washing liquid and compressed air from a main pipe 10 are branched into two systems of the first and second, that is, the upper and lower side A- and B-systems between connection pipes 13, 14 and a change- over valve 19 by the connection pipes 13, 14. For example, in such a state that paint is supplied to a coating gun 17 through the color change valve 11 on the side of the A-system, the flow passage of the system passing through the color change valve 12 of the B-system can be washed. Therefore, when the paint to a product to be painted is altered, only by washing the part from the change-over valve 19 to the coating gun 17, the next painting work can be rapidly performed within a short time.
